On the ultraviolet spectrum of t r a n s-1,3-butadiene

Abstract

The ultraviolet absorption spectra of trans‐1,3‐butadiene, 1,1,4,4‐trans‐1,3‐butadiene‐d₄, and trans‐1,3‐butadiene‐d₆ between 2300 and 1350 Å have been recorded and analyzed. Four Rydberg series were identified (δ=0.087, 0.21, 0.42, and 0.67). A transition‐by‐transition comparison of this analysis with those in the literature shows that several of the previously assigned transitions are misidentified. A continuum originating around 1450 Å is reported.
